Searching for Sessions Using Web GUI

Using Web GUI, you can search for all sessions, or specify certain criteria and display only sessions that match that criteria. Web GUI searches the current session table (CST) to find the matching sessions.

Note: Sessions must be running on a controlled device and that device must have sent an accounting start message in order to be found in the CST.

You can include wildcards in your search criteria to find sessions that match the leading or ending characters you specify. For example, enter AB* in the Select by User field to find all sessions for which the username begins with AB. Wildcards are only accepted for the Select by User and Select by NAS Name fields (text fields).

Leading wildcards are supported only in a trailing position. For example, "*bcd" matches any value and "abc*def" matches any value beginning with "abc".

Tip: To find all sessions, enter an * in the Select by User field with nothing entered for other fields.

Session Query Fields and Searchable Attributes

Table 103 describes the fields that appear in the Current Sessions page. You can use these fields as criteria when searching for sessions. For example, you can search for all sessions being run by a user with the username you specify.

Table 103: Session Query Parameters

Field

RADIUS Attribute

Description

Limit Sessions Returned to

Not applicable

Type the upper limit of number of sessions to be found.

The result is the lesser of this number or the system session limit.

See Setting Session Limits with Web GUI for more information about the effect of the Limit Sessions returned to field.

User-Name

User-Name

RADIUS username.

NAS Name

NAS-Identifier

Identifier set by the carrier when the device is deployed.

NAS IP

NAS-IP-Address

IP address of the controlled device.

Assigned IP

Framed-IP-Address

IPv4 address assigned to the user.

Session ID

Acct-Session-Id

Unique identifier assigned to a session.

Multi session ID

Acct-Multisession-Id

Identifier assigned to multiple sessions to link them together.

Calling Station

Calling-Station-ID

Station identifier (usually a telephone number or MAC address) of the user.

Called Station

Called-Station-ID

Station identifier of the NAD (the telephone number dialed by the user or the MAC address of the NAD)

To find sessions using the Web GUI:

  1. Select RADIUS Configuration > Current Sessions.

    The Current Sessions page (Figure 252) appears.

    For more information about the parameters in the Current Sessions page, see Table 103.

Page
  2. Enter a value in the Limit Sessions Returned to field if you want to limit the number of sessions found.

    For more information about the effect of the Limit Sessions Returned to field, see Setting Session Limits with Web GUI.

  3. Move your cursor on the parameter column header you want to use in the search and click the Down arrow. Then, move your cursor over the Filters check box and enter the searching criteria in the text box.

    Note: If you select or enter multiple criteria, the search finds sessions that meet all the criteria (Boolean AND).

  4. Click Query.

    The Current Sessions page (Figure 252) displays the sessions that match the search criteria.

Viewing Session Detail

To view session details using the Web GUI:

  1. In the Current Sessions page (Figure 252), select the session for which you want to view the details and click View.

    The Session Data dialog box (Figure 253) displays additional RADIUS attributes about the session.

    The Session Data dialog box has a different appearance for different device makes and models. The attributes that appear in the dialog box vary depending on the make and model of the controlled device. Different devices send different lists of attributes and values.

  2. Click Close after viewing the session details.

Deleting Sessions

Normally, the system maintains the information in the sessions list based on accounting information received from the RADIUS client. However, a user who has logged off may still be identified as active in the sessions list if communications between the RADIUS client and SBR Carrier fail or if either the RADIUS client or SBR Carrier is taken down for a period of time.

In most cases, SBR Carrier can correct such anomalies itself. For example, if a new user dials in to the same port on the same RADIUS client, SBR Carrier infers that the previous user must have disconnected and removes the entry.

You can manually correct the sessions list by selecting any entry and clicking Delete. This removes the user from the list and decrements the user’s connection count (if it is being tracked) by one. Any pooled IP address assigned to the deleted user is returned to the appropriate pool.

Note: Deleting a session deletes the session from the SBR Carrier Current Sessions Table (CST). However, the session remains active. To inactivate a session, you must perform disconnect which requires the optional Session Control module. For more information, see Overview of the Optional Session Control Module.
